You can imitate the classroom environment and practice several times before you say it. You have studied for so many years and listened to many teachers' lessons. Is there a type you admire and learn from others' strengths? It can be prepared within 40 minutes, so as to avoid the speech not being played out and the speech will not be circulated successfully.
I feel calm and relaxed when I speak. You don't need to think that there are professors interviewing teachers under me or something. Who didn't come from primary and secondary schools step by step? I didn't say Zhuge Liang didn't take his troops before he came out. Why should I have experience? It doesn't matter if your spoken English is not very good. Speaking English is sometimes much better than speaking Chinese. China people should also pay attention to your literary talent and expressive ability. Speaking English can express clearly, and you can also express your views from different angles without repetition. The interview teacher pays more attention to whether you have teaching potential, not necessarily the perfect teacher now. I don't know how many times a person will take the exam in his life. The interview is just one of them. May my words at least give you spiritual encouragement. Wish you success!
